At present, the simplest thing is that you go to the detention center to find a lawyer. You tell the lawyer that you have only met once, send a message, and then decide whether to take him to court (but this also needs the signature of your family, you can discuss it with his mother and go together). Pass a few words, usually there is not much money, and in some places 300,500 is enough. (There are also two thousand. . )
After meeting and leaving a message, you can decide whether to go to a lawyer for a lawsuit. Lawyers are useless in criminal cases, and it is not recommended to hire lawyers. Lawyers are used to deliver information. There is no other use.
See if any cheap lawyers will go in and pass on a few words.
Then there is the detention center to find acquaintances. Call the police. .
Writing letters, according to the law, criminal suspects can only contact their families with the permission of the public security organs. Do you think the police will allow it?
If you don't understand anything, just leave me a message. .
Please adopt it. Thank you.
